前言

HammerDB 是一个开源的数据库负载测试和基准测试工具，同时支持 Windows 和 Linux 平台。

️ 1. HammerDB简介

HammerDB 是一个开源的数据库负载测试和基准测试工具，同时支持 Windows 和 Linux 平台，可以针对 Oracle 、SQL Server、DB2、TimesTen、 MySQL、MariaDB、
PostgreSQL、Postgres Plus Advanced Server、Greenplum、Redis、Amazon Aurora、Redshift 等进行压力测试。
它主要模拟两种不同的测试模型：TPC-C 测试模型和 TPC-H 测试模型。相比于标准的 TPC-C 和 TPC-H，HammerDB 运行成本低，操作简单， 是服务器数据库压力测试
的很好选择。
• HammerDB 通过模拟 批发商的货物管理环境，实现了 TPC-C 测试模型，即在线事务处理（OLTP）的基准测试模型。测试结果由 TPC-C 吞吐率衡量，标准测试模型中
的单位是 tpmC（在 在 B HammerDB 是 中，测试结果的单位是 tpm，不是 tpmC。m tpm 表示每分钟的事务交易数量，tpmC 是 TPC-C 的事务交易单位）。
• HammerDB 通过模拟供应商和采购商之间的交易行为，实现了 TPC-H 测试模型，即在线分析处理（OLAP）的基准测试模型。测试结果由 TPCH Power 来衡量，该值
与数据量和交易平均时间有关，表示一小时内能够完成的复杂交易的数量。
关于 TPC-C 和 TPC-H 的详细介绍请参考 TPC 官方网站（http://www.tpc.org/）

️ 2. 容器部署

2.1 镜像下载

docker pull techerwang/oracle:centos76

2.2 创建容器

docker rm -f jemhammerdb

docker run -d --name jemhammerdb -h jemhammerdb \
-p 34389:3389 -p 42222:22 \
techerwang/oracle:centos76 init

docker exec -it jemhammerdb bash

2.3 Linux 下安装

wget https://github.com/TPC-Council/HammerDB/releases/download/v4.0/HammerDB-4.0-Linux.tar.gz

[root@jeames ~]# tar -zxvf HammerDB-4.0-Linux.tar.gz -C /usr/local/
[root@jeames ~]# cd /usr/local/HammerDB-4.0

2.4 相关校验

hammerdb>librarycheck

️3 . HammerDB压测MySQL

1.如果是Windows直接点击hammerdb.bat，如果是Linux需要调用图形化界面
2.windows平台压测，非常耗CPU

## 调用图形化界面
export DISPLAY=192.168.1.1:0.0
echo $DISPLAY

[root@jeames ~]# cd /usr/local/HammerDB-4.0
[root@jemhammerdb HammerDB-4.0]# ./hammerdb

注：生产环境压测，建议仓库数不少于100
